PM43599: SIGNATURE.GETPARAMETERS() THROWS UNSUPPORTEDOPERATIONEXCEPTION

APAR status

• Closed as program error.

Error description

• Applications which call java/security/Signature.getParameters()
  will always get a java/lang/UnsupportedOperationException with
  the following stacktrace:
  
  java.lang.UnsupportedOperationException
  at java.security.SignatureSpi.engineGetParameters
  at java.security.Signature.getParameters
  
  At Java 6.0 and above.
  
  java/security/Signature should be calling the SignatureSpi
  Implementation provided by the relevant Security Provider in
  use.
  However, Signature is actually making the call directly to the
  Abstract Superclass: java/security/SignatureSpi and not the
  implementation.
  
  This APAR is related to APAR IZ67447 which corrected the same
  problem for the singular functions getParameter and
  setParameter
  

Local fix

• Java 5.0 and below is not affected by this problem.
  
  The solution for this issue will be to call
  engineGetParameters() on the loaded SPI implementation.
  
  Contact Java Level 2 for an interim fix.
  

Problem summary

• The problem is caused when an implmented
  Signature.getParameters() method is called, which will directly
  call setParameter of interface Signature to throw an
  java.lang.UnsupportedOperationException
  

Problem conclusion

• This defect will be fixed in:
  6.0.1 SR1
  6.0.0 SR10
  .
  SignatureImpl.getParameters() method has been added to correct
  this.
  .
  To obtain the fix:
  Install build 20110813 or later
  

Temporary fix
